The man returned to Georgia on Valentine's Day, according to a police statement. That's when authorities say they were led to the 42 pounds of meth "base powder" contained in three fire extinguishers, the Atlanta-Journal Constitution reports.

"Agents believe this powder was destined for a conversion lab (a facility to turn the powder into crystal methamphetamine) somewhere in metro Atlanta," according to the statement.

The undercover investigation, in which agents say they successfully purchased meth from alleged members of the ring, resulted in the arrests of three men.
